Do diffrent measureing devices cause different conclusions?

In diffrent feilds of science, diffrent diciplines measure using different measuring scales. Does this cause a contextural change in the final conclusion. IE if a physicist publishes a paper with a selection of results. Will the measuremnts be misinterprated by another discipline?

Have there ever been any historical incidents where this has caused accidents?


Physical measurements are hard to misinterpret. The major sort of accident, of which you speak, is normally unrecorded and results from the same confusion which might cause an American cook, reading a European cookbook, to set the oven temperature too low because he interprets "200°" as 200° Fahrenheit.

This is not likely to happen in science since for about the past century scientists worldwide have used the "metric system" for measurements, including the Celsius temperature scale.

However, a great deal of philosophical confusion has been generated by incorrect application of scientific concepts by non-scientists. An egregious example is what seems (to this layman) as the preference in economics for mathematical models, even those which are far too simple to describe the real world, over verbal models which, while not as quantitative, give a better fit to observation. The over-use of Kuhn's word "paradigm" is another, and of course everyone is familiar with the way relativism has often been incorrectly tied to relativity.

For a while, Bohr's concept of complementarity was being pushed as a cure-all for seemingly irreconcilable philosophical constructs (Bohr himself was one of those doing the pushing), but that seems to have died down.

Asked the moral implications of his lifework in theoretical physics, Einstein replied, "None that I know of."
